Does anyone have a good range of values for overclocking these GPUs?

Currently I have it set in the MSI Afterburner program to:

110 Power
+100 mhz (memory)
Very conservative user define fan speed profile

I can add screenshots later hopefully. Some of my specs below.

i7-6700k
16gb DDR4 3000
ASUS Z170-AR
Zotac Amp Extreme GTX 980ti SLI
EVGA Gold 1300w PSU

No GPU is the same, you have to test your specific cards out for yourself. Just an FYI, you see more gains overclocking the core clocks then memory so I would start with that and find your maximum before you start pushing your memory.

What does your card boost to out of the box when its under load? Start off by increasing the core 15-20Mhz and run firestrike or heaven after each increase to ensure it is stable with no crashes or artifacts. Keep doing this until you do. Once you experience instability, then you can back it off -5Mhz and try again to find the best clock.

My card boosts out of the box to 1443Mhz and I was able to increase my core to +100 before I experienced DX11 driver crashes and hardfreezes. Once I increased my memory I had to back off my core a little for stability. Im now sitting at +75 core and +450Mhz memory stable. 1528Mhz/8000 Memory. Maxwell cards are very sensitive to temperatures so make sure you keep your GPU as cool as possible and have adequate case cooling. They also dont scale very well with voltage increases, it has very little effect mostly but sometimes it can help a little get that last push for stability.

Hope this helps and good luck!
